The Bieri-Neumann-Strebel Invariant of the Pure Symmetric Automorphisms of a Right-Angled Artin Group
We compute the BNS-invariant for the pure symmetric automorphism groups of
right-angled Artin groups. We use this calculation to show that the pure
symmetric automorphism group of a right-angled Artin group is itself not a
right-angled Artin group provided that its defining graph contains a separating
intersection of links
